I´m very worried and I need a professional opinion. In march a doctor took a small biopsy from my mouth and two weeks after that I kissed for quite some time with my ex (french kissing). I got worried that what if I got hiv from that kissing. I don´t think there was a lot of blood in his mouth but I do know that I have bad gums. 2 months after that kissing incident I took an hiv and sifilis test, they were negative. Now I wonder if I should repeat the hiv test, now it´s been more than 4 months. Thank you for your help!
